BURNER FOR LAMPS.

To aZZ whom it may concern:

Be it known that I, JOI-IN CLIFFORD, a citizen of the United States, residing at Colfax, in the county of Whitman and State of l/Vashington, have invented new and useful Improvements in Burners for Lamps, of which the following is a specification.

The invention relates to lamps and has for an object to provide a burner therefor.

The invention comprehends, among other features, a burner for lamps and which is arranged on the usual vessel or lamp body in a manner which will prevent any oil from leaking out of the lamp body if the same should be accidentally upset, thus also prevent-ing an explosion yof the lamp in the event that the wick is ignited at the time the lamp is upset.

The invention still further comprehends a structure whereby the gases forming on the surface of the oil in the lamp body will be readily and quickly carried out of the lamp body to the exterior of the lamp, thus further greatly minimizing the chances of an explosion when the lamp is ignited.

A still further embodiment of the invention resides in a structure of simple and durable construction and which consumes less fuel in a given period of time than the ordinary oil lamps now generally in use.

In the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which:

Figure l is a vertical sectional View of the lamp; Fig. 2 is a bottom plan view of the wick tube; and Fig. 3 is a horizontal sectional view taken on the line 3--3 in Fig. l.

Referring more particularly to the views, l disclose a lamp including a lamp body 11 adapted to contain oil or other fuel and provided with an opening 12 normally closed by a burner 123 supported on the lamp body, the said burner being of any preferred type and of the usual shape and including a base 11i which has threaded connection with the lamp body 11 to completely close the opening 12 and prevent any oil from leaking out between the lamp body and the burner, a bonnet 15 being mounted to swing on the base 14 to inclose the upper end of an elongated wick member 16, from which the usual wick 17 projects through a slot 18 in the Specification of Letters latent.

bonnet 15. A series of supporting members 19 are carried by the base illand extend up wardly to engage a lamp chimney 20 supported on the base. The usual wick controlling mechanism 21 is provided for advancing or retarding the wick 17 with respect to the bonnet and the wick member 1G, the said mechanism being supported on the base la in the usual manner.

The base 14- includes the threaded portion 22 mentioned heretofore as having threaded connection with the lamp body l1 to support the base thereon, and rigidly secured to the threaded portion 22 and depending therefrom is a wick tube 23 in which a greater part of the wick 16 is received, only a small end of the wick being adapted to extend exteriorly of the wick tube as shown, a stopper 2li consisting of a plurality of similar semicylindrical members 25 being arranged in the lower end of the wick tube to close the saine, the said members, however, being spaced apart to provide a slot 2G through which the projecting end of the wick extends, it being readily seen by referring to F ig. l that when the base let is supported on the lamp body l1 in the manner described, the wick tube 23 depends within the lamp body so that the small projecting end of the wick will absorb the fuel contained in the lamp body and convey the same to the upper projecting end of the wick which is to be ignited. New it will be apparent that by having the lower end of the wick tube closed up as mentioned, if the lamp is upset, the fuel contained therein cannot leak out of the lamp and cause an explosion, while the wick is ignited, inasmuch as the amount of fuel which is consumed at the upper end of the wick is absorbed by that portion of the wick in the wick tube so that the supply of fuel from the lamp body to the upper end of the wick is not direct and the wick tube constitutes an auxiliary chamber for the fuel so that at all times the portion of the wick in the wick tube will be thoroughly saturated with the fuel and the fuel in the lamp body will only be absorbed by the wick in the wick tube as the fuel with which the wick is saturated in the wick tube is consumed, at the upper end of the wick. It will, therefore, be apparent that no fuel can flow through the wick tube nor from the interior of the lamp body to the exterior thereof in view of the threaded connection of the base with the lamp body.

In order t'o 'further prevent 'explosion a gas tube 27 depends from the threaded portion 22 and adjacent the wick tube l23, the

upper end of the gas tube 27 terminating in an outlet open-ing 28 and the` lower end having connected t'her'e'to` a flexible hose 29 which has connection with :a Iioat i3() adapted to repose on the surface of the fuel construction thereof, it will be 'understood that various slight changes may be made without departing from the spirit 'of the invention, the scope of the invention being dened in the appended claims.

Having thus described my invention, I claim:

l. In a burner for lamps, the 'combina'- tion with a lamp body, of a burner member carried thereby, a gas tube supported on the burner member and depending in the lamp body, a float reposing on the surface of the f-uel inthe lamp body, and a hose having connection with the float and the gas tube for conveying any gas in the -la-nip body eXteriorly of the said burner member.

2. In a burner for' lamps, the combination with a lamp body, of a burner member carried thereby, a Wick tube depending from the burner member, means carried by the burnerfor adjustably supporting a wick thereon, with the lower portion `of the :said wick fconfine'd in the said wick tube and an 'end "of the wick projecting exteriorly of the wick tube and depending in the fuel in the lamp body, fand la stopper zClosing the lower end of the wick tube and Yconsisting of a plurality of similar semieylindrical members spaced 'apart to provide a slot through which the projecting end of the said wiel: extends.

In testimony whereof I aHi'X my 'signature in presence of two witnesses.

JOHN CLIFFORD.
